I have bought a new pc with Windows 11 home pre-installed and set Mozilla Firefox latest version as default browser ...the issue i am having is placing add-on extension shortcut icons on toolbar. I installed Norton Safe Web and this installed ok and is listed in extension control panel and when i click puzzle icon Norton Safe Web is not shown under manage shortcuts nor can i see option to Pin to Toolbar. Have tried several attempts but still get nowhere.I uninstalled Mozilla Firefox...restarted pc ... did a fresh install of Mozilla Firefox without altering any settings..re-installed Norton Safe Web and still cannot see option to Pin to Toolbar.Clicking the gear icon does not help Have i missed a step somewhere ?

I installed the Firefox browser (version 113.0.2 (64-bit)) onto a new PC running Windows 11. When attempting to clean up the Firefox cache with another utility, I noticed that the amount of space recovered was much smaller than expected. When I tried to check my profile using the Troubleshooting Information page (to open the folder) I received a message that the location was not available. I double checked with Windows Explorer and this was the case. Searching for "cache2" in Explorer located the folder/directory in a different location.

The Firefox Profile Folder should be in this location, according to Firefox's Troubleshooting Information page (anonymized information in square brackets):

C:\Users\[username]\AppData\Roaming\Mozilla\Firefox\Profiles\[character string 1].[profile name]

The best I can tell, the actual Profile Folder created in Windows 11 is located here:

C:\Users\[username]\AppData\Local\Packages\Mozilla.Firefox_[character string 2]\LocalCache\Roaming\Mozilla\Firefox\Profiles\[character string 1].[profile name]

The cache folder for the profile is located here:

C:\Users\[username]\AppData\Local\Packages\Mozilla.Firefox_[character string 2]\LocalCache\Local\Mozilla\Firefox\Profiles\[character string 1].[profile name]\cache2\entries

I am not sure if this situation is unique to me, or if this is a common occurrence with Windows 11.

The use of the Packages folder may be the result of installing an application that is not fully "Windows 11-native" or it may just be the new way Windows deals with some applications. I am not sure if the data in character string 2 is consistent, or if it is a unique string created by Windows when Firefox was installed.

If I go to the Settings and clear data, the folder that is a sub-folder of Packages is cleared, so Firefox "knows" where the data is, but the Troubleshooting Information page is confused.

If this is a common occurrence, a tweak to this page in a future release would be helpful. If it is a rare occurrence, a help article may be, well, helpful.

Thanks.

Hello, I wanted to restore Firefox to start clean. I wanted anyway to reinstall my (few) extensions, all of which are safe and well known. When I do that, though, their icons don't show up in the toolbar. When I open the "customize toolbar" setting, extension icons aren't there. So there's no way to add them to toolbar.

I tried all possible methods: - "Restore Firefox" and resync my account (extensions are reinstalled but icons not shown in toolbar / customize toolbar) - "Restore Firefox", not syncing, and manually installing extensions (icons still not shown in toolbar / customize toolbar) - Uninstall Firefox, delete everything in Profiles folder, reinstall Firefox. Same behavior.

So, it seems it's something not related to a broken profile, since a fresh profile, with no syncing, does not fix the issue.

Any clue of what I could try? Thanks!

Chrome and edge have "apps" that let me make websites into separate windows and treat much like apps. I can do this for my calendar, notes, and timer websites, for instance. I have yet to find a feature like this for Firefox. Does it exist? Is there a roadmap where this is being worked on?

Thank you

Hi,

I've been encountering a strange issue where colors (especially whites) in the video player are super washed out. This only happens when HDR is turned on in windows, and only happens in my Firefox Developer Edition installation (normal firefox works fine). It also doesn't show up in any windows screenshots - the colors revert to normal when I'm in the screenshot GUI. I've attached photos below of a youtube video, the left is firefox DE and right is normal firefox, both in and out of the screenshot GUI so you can see the difference.

I'm on Windows 11, and I'm not sure what caused the issue. I've tried both refreshing and reinstalling firefox DE to no avail. Pretty stumped on this one, and would appreciate any help!

Some fonts randomly use an ugly, blocky font for no reason. I've seen it happen on some web pages and PDFs but not on all. I have tried other browsers but it is a Firefox-only problem. It doesn't occur in troubleshooting mode as shown in the attached picture. Any help to resolve this would be greatly appreciated!

I opened about:certificate to make sure my local O/S certs were in order and noticed the Servers tab and after opening it saw that DigiNotar Root CA was the one and only entry. I know all about the DigiNotar fiasco and how their root cert was left enabled after the NL government took over in order to prevent a bunch more problems. However, I don't understand why that cert is listed in my Servers tab and why it isn't anywhere in my Settings -> Certificates options window. I have used a couple self-signed certs in the past for localhost web server stuff where I got tired of the SSL warning over HTTP on my local domain, but otherwise only have my PGP key and haven't messed with anything otherwise. Should I be worried? This thing happened several years ago and the Root Cert I have is listed as expiring in about a year and a half.

Running Windows 11 Pro and Firefox 114.0.1 (64-bit)

I was signed in with FF and synced all data. I needed to re-install Windows, after installing FF on fresh windows and logging into FF account - nothing is synced. What have i've done wrongly?

A white screen occurs when browsing the web. If you turn off "Use recommended performance settings" and "Use hardware acceleration when available" the problem is fixed, but then the browser slows down. Can this be fixed in another way?

Firefox 114.0 (64-bit) / Windows 11 Home 21H2

Why has this started up again? Pdf files are automatically downloading to my computer when all I want to do is look at the file. So many files that now need to be trashed after looking at them. This problem has happened in the past, but was resolved, only now I am finding it happen again. I do not want to have files saved unless I want to save them, not Firefox deciding that any file I open should be saved. I have Windows 11 & Firefox Version 113.0.1. Is there a way to revert to an older version of Firefox?

Hail all:

Now, I have 2 Google accounts: My private one, and a Corporate Account, used for work. I always signed out of my normal window from the active account to the Corporate Account and vice versa, depending on which I needed to check. A common occurrence for many people.

But I noticed long ago, that in Private Window ... I seem to be signed out, opening Google in it. I use Private Window to avoid unnecessary clutter from sites dropping their stuff on my Temp folder. I hate clutter ... severe Asperger's.

I was thinking ... if I keep my private Google Mail on the prime non-Private window, can I sign in while this is open (and stays open) into my Corporate account in my Private Window?

If so, this would save me quite a bit of hassle, having to log out several times a day from my main, private account/mail and into the Corporate account mail, and when done vice versa to me private account mail.

Thank you.

Hi

Well Firefox did it again. I had tabs on the bottom where I wanted them and they broke this again in the update I just got.

Any idea how to move them back down to the bottom? This is the userchrome.css coding I was using that worked fine before the update

I have been unable to get Firefox to open in my new windows 11 build. I install Firefox, try to launch the program and get a message that an instance of Firefox is running and must be closed to run my requested launch. I use taskbar and there is no instance of any Firefox process running. I have uninstalled and reinstalled and the same message comes up. I installed an old version of Firefox from 2012 and it works but I get security notices about it and there is no update option available. Is Microsoft blocking my use of Firefox? I went to the Microsoft store and downloaded their version and the same thing happened. Any suggestions will be greatly appreciated.

I use the closed captions (CC) in YouTube videos with FireFox. Lately I have been seeing videos that seem to misbehave. At the very start of the video, ALL the captions display at once, one after the other. Then, as play continues there are no more captions. Most videos still show captions normally, that is, captions appearing only when the dialog matches them. But a few videos misbehave by showing all the captions at once. Here is one such video.

https://www.youtube.com/watch?v=ZgqJ5wQF944

I noticed this misbehavior within the last month and assumed that the video was doing something peculiar with the timing of the captions. But when I use the YouTube Show Transcript option to display the captions and associated timing outside the video, the transcript looks quite reasonable.

One further oddity, if I take that same URL and load the video in a different browser, for example, Chrome, the captions are displayed normally.

I've included a screen shot of the video in YouTube showing all the captions displaying at once.

I am using Firefox 114.0.2 address bar only, no search bar. I do not remember when it was happened, but today when I want to copy and paste page address I found out that address bar did not display the page address as previous version, just display the words I searched as a search bar (if the search bar is enabled, and typed in search bar then push enter, address bar will display address of search result page, and search bar will keep displaying the words in it). I attached my screenshot below. Using another tab and "switch to tab" feature by Firefox, I found out the page address. In my screenshot, I typed "test" and using Google to search (I also tried Bing, Wikipedia and more and all of them have the same problem with their owned link) and the page address should be "https://www.google.com/search?client=firefox-b-1-d&q=test" but even I paste this link into the address bar, it will only display "test" like the pic. I think it is a trim feature but I do not which preference I should edit in about:config. I have set "browser.urlbar.trimURLs" to false for displaying http and www, but it is not work this time.
